INTRODUCTION

Congratulations on purchasing your new CTEK professional switch mode battery charger. This charger is part of a range of

professional battery chargers from CTEK SWEDEN AB. It represents the latest technology in battery charging with charging and

analysis in eight steps with temperature compensation. Read this User Manual and follow the instructions carefully before

using your new charger.

SAFETY

• The charger is designed to charge lead acid batteries. Do not use the charger for any other purpose.

• Wear protective goggles and turn your face away when connecting or disconnecting the battery!

• During charging, the battery may emit explosive gases. Therefore it is essential to avoid any sparks in the immediate vicinity.

• Ensure good ventilation when charging.

• The charger should not be covered.

• Battery acid is corrosive. If any acid comes into contact with skin or eyes, rinse immediately with plenty of water and seek

immediate medical attention.

• Never charge a frozen battery.

• Never charge a damaged battery.

• When using outdoors the charger has to be positioned horizontally with the long side or top side turned up.

• Do not place charger on top of the battery when charging.

• Always check that the charger has switched to maintenance charging before leaving it unsupervised and connected for

prolonged periods of time. If the charger has not switched to maintenance charging within three (3) days, this is an indication of a

fault. The charger must then be manually disconnected.

• All batteries have a limited lifetime. Any battery failure during charging is normally dealt with by the charger’s advanced control,

but a battery could develop unusual faults. Do not leave the charger unsupervised for long periods.

CHARGING

Connecting the charger to a battery ﬁtted in a vehicle

1. The power cord should be disconnected when connecting or disconnecting the battery leads.

2. Identify the battery terminal that is grounded (connected to the chassis). The negative terminal is normally the grounded post.

3. Charging a negatively grounded battery. Connect the red cable to the positive terminal on the battery and the black cable to

good metal engine ground away from the battery. Ensure you do not connect the black cable to fuel lines or sheet-metal body

parts.

4. Charging a positively grounded battery. Connect the black cable to the negative terminal on the battery and the red cable to

good metal engine ground away from the battery.

Ensure you do not connect the black cable to fuel lines or sheet-metal body

parts.

Connecting the charger to an out of vehicle battery:

1. The power cord should be disconnected when connecting or disconnecting the battery leads.

2. Connect the red cable to the positive terminal on the battery and the black cable to the negative terminal.

If the battery leads have been connected incorrectly, the

reverse polarity protection system will ensure that neither the charger

nor the battery are damaged.

Start charging

1. Connect the charger´s AC cord to an AC Power Supply. The charger will indicate POWER, yellow indication lamp (B).

2. The lamp for completely discharged battery (1) will illuminate if the battery’s voltage is less than 12 V for MULTI XS 25000 and

XS 25000 or 24 V for MULTI XT 14000 or XT 14000.

3. Normal charging will be indicated by the following lights: completely discharged battery (1), bulk charging (2), absorption

charging (3) or maintenance charging (4). When the maintenance charging lamp illuminates the battery is fully charged. Charg-

ing will start if the voltage drops. The charger can normally be connected for months. Reconditioning (only on MULTI XS 25000

and MULTI XT 14000) is indicated by the lamp (5) illuminating.

4. If the battery leads have been connected incorrectly, the reverse polarity protection system will ensure that neither the charger

nor the battery are damaged.

5. If nothing happens. If the lamp indicating the setting and the power lamp remain lit but no other lamp illuminates, the connec-

tion to the battery or chassis may be poor or the battery may be faulty. Another cause may be a lack of voltage in the AC Power

Supply. Begin by improving the connection between the battery and charger.

6. Charging can be stopped at any time by disconnecting the charger’s AC cord. Always disconnect the AC cord before discon-

necting the battery leads. When you stop charging a battery installed in a vehicle you should always disconnect the battery lead

from the chassis before disconnecting the other battery lead.

IMPORTANT INFORMATION FOR MULTI XT 14000 and XT 14000 Please note that the battery pack in the 24 V system in most

cases consists of more than one battery. They are linked up to the 24 V

system, but the individual batteries generally have a

lower voltage. Therefore it is important for the charger to be connected correctly.

BATTERY TYPES AND SETTINGS

The XS 25000 and XT 14000 are programmed according to “PROGRAM DESCRIPTION” with ﬁxed settings. MULTI XS 2500

and MULTI XT 14000 can easily be set for different types of batteries or conditions. The following recommendations should,

however, only be seen as guidelines. Please consult the battery manufacturer for further instructions.

Settings are made by pressing the “MODE-button “ and stepping forward one press at a time until the required mode is reached,

the button is then released. After about 2 seconds the charger activates the selected mode. The selected mode is saved in a

memory in the charger and remains there even if the charger is disconnected from battery and mains.

NORMAL

NORMAL - Normal setting for wet batteries, maintenance free and for most Gel batteries. Some Gel batteries

prefer a slightly lower charging voltage. Please consult the battery manufacturer when in doubt.

SUPPLY

SUPPLY - The charger operates at a constant voltage. This is the maintenance mode for applications where

maximum capacity from the battery is important, like ﬂoor sweepers and golf carts. Note that the Spark

protection function is suppressed in this mode.

RECOND

RECOND - This mode is used to recover deep discharged ﬂooded batteries where you could expect a

stratiﬁed acid (high acid weight in the bottom, low on top). Check with battery manufacturer when in doubt.

Use this mode with care, because the high voltage will cause some water loss. 16 V is normally no problem

for electronics in 12 V system, or 32 V in 24 V system. Consult your supplier when in doubt. Life of light

bulbs will be reduced at higher voltage. Try to disconnect light from the battery during this phase. Maximum

effect and minimum risk for electronics is achieved by charging a disconnected battery.

CHARGING PHASES

MULTI XS 25000, XS 25000, MULTI XT 14000 och XT 14000 charges and analyses in eight fully automatic steps.

MULTI XS 25000 and MULTI XT 14000 have three different operating modes, see Battery Types and Settings.

The battery charger has an 8-step fully automatic charging cycle:

Desulphation

Desulphation with pulses recovers sulphated batteries. Indicates with lamp 1.

Soft start (Lamp 1)

Start mode for the charging cycle. The charging current is limited. The start phase continues until the battery’s terminal voltage

has risen above the set limit, at which point the charger switches to bulk charging. If the terminal voltage has not passed the

voltage limit within the time limit, the charger switches to fault mode (lamp 0) and discontinues the charging. If so, the battery is

faulty or its capacity is too large.

Bulk (Lamp 2)

Main charge when 80% of charging takes place. The charger delivers maximum current until the terminal voltage has risen to the

set level. Bulk has a maximum time, at which point the charger automatically switches to Absorption.

Absorption (Lamp 3)

Complete charge up to virtually 100%. The terminal voltage is maintained

at the set level. During this phase the current tapers

successively. Once the current has tapered to the set limit, this phase switches to being timed. If the total time for Absorption

exceeds the time limit the charger automatically switches to maintenance.

Analysis (Lamp 3)

Testing self-discharge. If self-discharge is too high, charging is discontinued and fault mode is indicated.

Maintenance charging - Float (Lamp 4)

Charging at constant voltage.

Maintenance charging - Pulse (Lamp 4)

Charging varies between 95% and 100% state of charge. The battery receives a pulse when the voltage drops and keeps the

battery in perfect condition when it is not in use. The charger can be connected for months at a time. The charger continuously

measures the terminal voltage to determine whether a charging pulse should be initiated. If the battery is loaded and/or the

battery’s terminal voltage drops the charger starts a charging pulse until the terminal voltage reaches the set level. The charg-

ing pulse is then discontinued and the cycle is repeated inﬁnitely.

If the terminal voltage drops below a lower limit, the charger

automatically goes back to the beginning of the charging curve.

Recond (Lamp 5) (only on MULTI XS 25000 and MULTI XT 14000)

This mode is used to recover deeply discharged ﬂooded batteri

es. Recondition of deep discharged batteries. The voltage

increases with reduced current for a limited time period. The higher voltage starts some gassing and mixing of the acid, which is

beneﬁcial for both battery capacity and expected life. Note that the battery could emit explosive gas during Recond. R

econd is

performed between Analysis and Ma

intenance.

TEMPERATURE COMPENSATION

MULTI XS 25000, XS 25000, MULTI XT 14000 and XT 14000 have a sensor cable placed together with the battery cables. The

units will automatically adjust the charging voltage if the temperature deviates from +25 C. A high temperature lowers the voltage

and freezing conditions is handled by higher voltage.

The temperature is best measured on or very close to the battery. Therefore always place the sensor as close to the battery as

possible when charging. The sensor cable could be prolonged or cut to length with the same functionality. A short-circuited or

disconnected sensor is indicated by lamp A. The charging voltage is then adjusted to the +25 C condition.

*) Back current drain is the current that the charger drains from the battery if the AC cord is disconnected.

**) The quality of the charging voltage and charging current are very important. High current ripple heats the battery and ages

the positive electrode. High voltage ripple can damage other equipment connected to batteries. The battery chargers from CTEK

produces very high quality voltage and current with low ripple.

***) IP 44 cannot be guaranteed if the charger is not positioned horizontally with the long side or top side turned up.
